COMBINED ICE-HOUSE AND COOLING -CHAMBER.

SPECIFICATION forming part of Letters Patent No. 301,468, dated .Tulyfi, 1884.

l Application filed October 26, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN ALEXANDER, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Combined Ice-Houses and Cooling-Chainbers, of which the following is a specification.

The object of the invention is to construct an ice-house in which the cooling property of the ice may be economically and effectually secured; and it consists, essentially, in an icehouse having a wall between the ice-chamber and the cooling-chamber, a cold-air flue extending from the bottom of the ice-chamber into the bottom of the cooling-chamber,with a hot-air flue extending from the ceiling of the cooling-chamber into the top of the icechamber, the ceiling of thecooling-chamber being so arranged that the air near its .top, which is of course warmer than the air at its bottom, shall be gradually cooled before it reber 13, it is to a certain extent warmed by coming in contact with the contents of the cooling-chamber, and also from the fact that it is separated from the ice. As it grows warmer,- it will naturally ascend, coming in contact with the slanting ceiling E. This ceiling, it

will be noticed, slants from the top of the cooling-chambers door F to a point near the wall 0 a little below the warm-air flue G. From this point the ceiling extends vertical- 1y, as indicated, till it reaches the higher ceiling, H, which extends into the cold-air chamber A, and also forms the top side of the warnrair flue G. The space between the vertical portion of the ceiling E and the wall 0 being less than the width of the chamber, the warm air passing up the slanting portion of the ceiling is in a measure checked before it reaches the flue G, which admits it into the ice-chamber A. By thus checking the warm holes, J, in the side of the ice-house.

air condensation is prevented from taking place on the ceiling E, as the air is gradually cooled before it comes in contact with the cold air on the ice-chambers side of the wall 0. It will be noticed that the ice-chan1- her A has a ventilating-flue, I. This fine provides effective ventilation for both chambers.

\Vith the view of maintaining a circulation, and at the same time admitting fresh air into the ice-house, I make one or more draft- The air from the outside will enter these holes, and after passing through the ice and cooling chambers will flow out again through the ventilator I.

It will be noticed that there is a double roof provided for the ice-chamber and coolin g-chamber, and, further, that the inner roof or ceiling slants toward the ventilator I. This double roof leaves an air-space, L, between.

the outer and inner roofs. With the View of preventing this air-space becoming heated I form a series of holes, a, around the ventilator 1, thereby forming communication between this ventilator and the air-space L.

hat I claim as my invention is 1. In an ice-house having a wall between the ice-chamber and the cooling-chamber,with a cold-air flue at the bottom of the wall and a warm-air flue at the top, the combination of a slanting ceiling from the top of the coolingchambers door to a point near the separating-wall a little below the warm-air flue, from which point the ceiling extends in a vertical direction till it meets an incline ceilingextending into the coldair chamber, substantially as and for the purpose-specified.

2. .In an ice-house having a wall between i the ice-chamber and the cooling-chamber, with a cold-air flue at the bottom of the wall and a warnrair fine at the top, the combination of a slanting ceiling from the top of the cooling chambers door to a point near the separating-wall a little below the warm-air flue, from which point the ceiling extends in a vertical In presence of CHARLES C.
